Pulmonary Embolism
Pneumologie. 2021 Oct;75(10):800-818. doi: 10.1055/a-1029-9937. Epub 2021 Oct 18.ABSTRACTPulmonary embolism (PE) is a life-threatening disease and the third most frequent cardiovascular cause of death after stroke and myocardial infarction. The annual incidence is increasing (in Germany from 85 cases per 100000 population in the year 2005 to 109 cases per 100000 population in the year 2015). The individual risk for PE-related complications and death increases with the number of comorbidities and severity of right ventricular dysfunction. Using clinical, laboratory and imaging parameters, patients with PE can be stratified ...

Pharmacokinetics of Direct Oral Anticoagulants in Patients With Atrial Fibrillation and Extreme Obesity
Clin Ther. 2021 Aug 5:S0149-2918(21)00247-2. doi: 10.1016/j.clinthera.2021.07.003. Online ahead of print.ABSTRACTPURPOSE: Direct oral anticoagulants (DOACs) are recommended in preference to vitamin K antagonists (VKAs) for stroke prevention in patients with atrial fibrillation (AF) eligible for oral anticoagulation therapy; however, data and clinical experiences supporting the use of DOACs in patients with a body mass index ≥40 kg/m2 or weight >120 kg remain limited. The aim of this study was to evaluate the pharmacokinetic properties of DOACs in patients with AF and extreme obesity.METHODS: We enrolled all consecutiv...

Oral anticoagulation for patients with atrial fibrillation in the ED: RE-LY AF registry analysis
AbstractOral anticoagulation (OAC) reduces stroke risk in patients with atrial fibrillation (AF). We sought to determine predictors of OAC initiation in AF patients presenting to the emergency department (ED). Secondary analysis of the RE-LY AF registry which enrolled individuals from 47 countries between 2007 and 2011 who presented to an ED with AF and followed them for 1  year. A total of 4149 patients with AF as their primary diagnosis who were not already taking OAC and had a CHA2DS2-VASc  ≥ 1 for men or ≥ 2 for women were included in this analysis. Of these individuals, 26.8% were started on OAC (99.2% vi...

Antithrombotic treatment management in low stroke risk patients undergoing cardioversion of atrial fibrillation & lt;48 h duration: results of an EHRA survey
AbstractData supporting the safety of cardioversion (CV) of atrial fibrillation (AF) without anticoagulation in patients with AF duration<48  h are scarce. Observational studies suggest that the risk of stroke in these patients is very low when the definite duration of the AF episode is of<48  h and the clinical risk profile as estimated through the CHA2DS2VASc score is low (a score of 0 for men and 1 for women). As the recent 2020 European Society of Cardiology (ESC) guidelines indication for this clinical scenario is based mainly on consensus, we sent out a survey to assess the current clinical practice on anti...

Abbott Wins Approval for CATALYST Trial for At-Risk Stroke Patients
This study is an extremely important step in assessing the Amplatzer Amulet as an effective non-prescription drug alternative for patients with AFib who are at an increased risk for ischemic stroke." In an email sent to MD+DI, Abbott wrote, “We already have an Amulet IDE trial underway that is intended to support our submission for approval in the U.S. for Amplatzer Amulet. The newly announced CATALYST trial will support our submission for an expanded indication for Amulet as a safe and effective alternative to NOAC drugs for patients with atrial fibrillation and at risk of stroke.” Abbo...

Reducing delays to administration of prothrombin complex concentrate in patients with vitamin K antagonist-related intracerebral haemorrhage.
Abstract BACKGROUND/AIMS: Four-factor prothrombin complex concentrate is the first-line treatment in vitamin K antagonist-related intracerebral haemorrhage. Early administration is associated with improved patient outcomes. A quality improvement project investigated delays in prothrombin complex concentrate administration in vitamin K antagonist-related intracerebral haemorrhage in order to reduce the time from computed tomography scan confirming intracerebral haemorrhage to prothrombin complex concentrate administration (scan-to-needle time). METHOD: Twenty patients were identified by retrospective audit ove...

Is there a role for low-dose DOACs as prophylaxis?
Authors: Cohen AT, Hunt BJ Abstract The direct oral anticoagulants (DOACs) have transformed the management of thrombotic disorders. Large clinical trials have demonstrated that DOACs can replace vitamin K antagonists (VKAs) in the 2 existing major indications for anticoagulation: the prevention of stroke in atrial fibrillation and the acute treatment and secondary prevention of venous thromboembolism (VTE); this literature is widely known. In this article, we will concentrate on the less well-discussed benefits of the use of DOACs-using low doses as primary and secondary prophylaxis in both venous and arterial thro...

Management of oral anticoagulation in very old patients with non valvular atrial fibrillation related acute ischemic stroke
AbstractThe optimal management of oral anticoagulation (OAC) in the acute phase of non valvular atrial fibrillation (NVAF)-related acute ischemic stroke (AIS) remains controversial, especially in very old patients. Therefore, the aim of our study was to evaluate the practical management of OAC in this context. We conducted an observational retrospective study on patients 85-years old and older admitted to two Italian hospitals for NVAF-related AIS. For each patient, clinical and brain computed tomography data were recorded. Type of OAC (vitamin K antagonists, VKAs or Direct Oral Anticoagulants, DOACs), dosage and starting ...

Low persistence to rivaroxaban or warfarin among patients with new venous thromboembolism at a safety net academic medical center
This study evaluated 90 day persistence among patients prescribed rivaroxaban or warfarin for the treatment of acute VTE at an academic safety net hospital. We conducted a single center, retrospective cohort study of 314 consecutive patients newly prescribed rivaroxaban or warfarin for acute VTE between January 2016 and July 2017. Primary outcome was 90 day persistence, and secondary outcomes included 90 day readmission and/or ED visit, time to 90 m day readmission and/or ED visits, and attendance of direct oral anticoagulant education class. Of 314 patients, 78 were prescribed warfarin and 236 rivaroxaban. Patients had a ...
